Makes sense, but won't work in my situation.  To make my Xcode  
project more configurable for formats that require optional external  
libraries (on OS X), I do these formats as plugins.  I know Frank has  
told me that this is an unsupported use of plugins, and partly for  
this very reason - format loading order.

For a quick immediate fix for the bug, this sounds like a reasonable  
workaround.  I can adjust my Xcode project somehow.  For a 'normal'  
configure-make-install build on OSX it wouldn't be a problem.

Frank, when I was thinking about this, and my excessive use of  
plugins, I wondered if GDALAllRegister() could be changed a bit: do  
some of the plugin checking and loading there directly instead of at  
the start in AutoLoadDrivers().  Then, whether it's a plugin or  
builtin, formats could still be loaded in a particular order.   
Something like:

#ifdef FRMT_netcdf
     // check for existence of plugin version of it
     // load it if found

Just a thought.
